ossicle

A small bone, especially one of the tiny bones, the auditory ossicles, in the middle ear that link the ear-drum to the inner ear. From the outside-in, the auditory ossicles are the malleus, the incus and the stapes.

ossicle

any of the bones in the middle ear connecting the eardrum to the oval window. In mammals there are three ossicles (MALLEUS, INCUS and STAPES). In reptiles, birds, and many amphibians, only a single bone (the COLUMELLA AURIS) is present.

There are many factors affecting success rates of reconstruction interventions, such as the condition of middle ear mucosa, condition of ossicles, extent of the disease, surgical technique, patient age, or the surgeon's experience.

In all cases, no injury happened to auditory ossicles. Conclusions: This exploratory study demonstrated the safety of the newly developed image-guided minimally invasive cochlear implantation assisted by the bi-planar device and established the operational procedures.

Another evolutionarily important structure in the skeleton of sea stars is the odontophore ossicle. Discussion about its origin, form, size, and position among asteroids has been ongoing for decades (Mooi and David, 2000; Gale, 2011).
